I'm not sure I would call the Mountain West "the top level of the NCAA" but I understand what you are saying about jumping up from FCS to FBS. I will say that NDSU would probably be a middle tier FBS team, so they likely had a lot more talent that the bulk of their opponents.
I don't necessarily believe that Lance deserves any more heat that Mac Jones probably does for throwing to wide open guys. It's definitely something that factors into the evaluation, without question.
Hurts I'd probably wait on making that comparison yet because it was also acknowledged that Philly had one of the worst WR corps in the NFL. Lamar Jackson was a 57% career passer in college but is a 64% passer in the NFL(although he did start his career as a 58% passer as a rookie).
I do agree that he will probably need significantly more development time than the rest of the top 4 QB's and will likely be the most reliant on designing an offense to make him successful. But, perhaps he can make the sort of progression that Josh Allen has over his career, which is to start out as a fairly unimpressive passer and bloom into an MVP caliber player.
